♦ Normally a radiator or towel radiator need a thermostatic radiator valve. Thermostatic Radiator Valves (TRVs) sense the air temperature around them and regulate the flow of water through the radiator which they are fitted to. They do not control the boiler but should be set at a level that gives you the room temperature you want. Except for these functions, a smart radiator valve gives you exact control of every radiator in your home from an app on your phone. It will make you more convenient to set a exact temperature, schedules to heat your radiator or warm your room or turn them off by the phone, whatever you are on home or outside.

♦ With the help of a smart programmable radiator valve, you can control the radiators when you do not need to heat your room and control the heating temperature of individual room. In this way, it will greatly save the energy and help you to save your bills of energy.
